Abstract

Background RA has a substantial societal effect in terms of costs, disability and lost productivity, with much of the costs occurring outside the healthcare system (1,2). However, the calculatedcosts of RA vary considerably depending on countries studied and methods used (3).

Objectives The objective of this study wasto evaluate the influence of morning stiffness on productivity at work and to estimate the work-related economic consequences of morning stiffness in 11 European countries.

Methods The original sample comprised 1061 RA patients from 11 European countries (Belgium, Denmark, Finland, France, Germany, Italy, Norway, Poland, Spain, Sweden and UK). They had symptoms of morning stiffness for more than six months, three or more times per week. Data were collected by interviews using a structured questionnaire translated into local languages. Women comprised 77.9% of the sample, the average age was 50.4 years and 84.3% had RA diagnosed for more than 2 years. Based on the average working time in EU countries (4) in all time-based cost estimates the numbers of active working hours per year was estimated to be 1568. The annual level of gross income reported by the patients was used to obtain individual time-based cost estimates.

Results Overall costs of RA-related morning stiffness was calculated to be 27712€ per patient per year, varying from 4965€ in Spain to 66706€ in Norway. On average 96% (77-99%) of the overall production losses were attributed to early retirement, with a markedly lower level (77%) in Italy than in other countries (p<0.0001). The proportion of patients who reported retirement due to morning stiffness showed considerable variation across the countries represented in the study, being relatively low in Italy but much higher in Finland, Denmark, UK and Poland. Also the productivity losses caused by late work arrivals, sick leave and working while sick were considerable. Overall, the annual cost of late arrivals (6-847€) was approximately half of the costs attributed to sick leave (0-1506€) and working while sick (0-1090€).

Conclusions Morning stiffness due to RA causes significant production losses and is a significant cost burden throughout Europe. There seem to be notable differences in the impact of morning stiffness on productivity between European countries.
